Said pendant comprises a substantially insaid leaf in the same plane as the table top. A 65 slight inward movement of the table top will then bring the edges 35 and 36 of the leaf and .table top into overlapping engagement as shown in Fig. 5.

It will be noted in Fig. 5 that the hook portion 27 of the pendant 25 is in approximate engagement with the stop lug 29 and that when it is desired to move the leaf 18 to its normal position beneath the table top, an initial pull outward of the table top will cause the hook 27 toengage the stop 29 and pull the projecting arms and leaf 19 downward. This will cause the springs 33 to be moved slightly below their dead center ff to' maintain the parts in the position shown when the leaf is moved inward. After moving said leaf inward it will again assume the position shownY in Fig. 2.

It will thus be observed that the operator can manipulate the movement of the leaf 19 from one n end of the table and all operations required to project and retract the leaf, with the exception of the manual movementof the'table top, are automatic.

It will also be observed `that there will be a natural tendency for the leaf to remain in close iittingengagement with the table top when open as indicated in Fig. 5, due to the inclined position of the supporting arms 21. i

lWhilethe invention has been shownfand described in its preferred form, vit will beV understood that certain changes and variations may be made in the specific structure provided for carrying out the invention, withoutrhowever departing from the spirit of the invention as dened in the appended claims. i f' Having thus described this claimed is: v
